[SOLVED] redirecting SPAM problem.

Hi,
I'm new in this forum, and new with zimbra.
I was installing ZCS and all works fine. But i have just one problem:I need to redirect ALL spam mails to another mailbox AND don't deliver to original destinations.

To do this i was studing a few hours and found something like
edit /opt/zimbra/conf/postfix_header_checks.in (to replace the "postfix_header_checks" file after restart)
and paste this rule:
/^X-Spam-Flag: YES$/ REDIRECT my@mail.com

but it doesn't WORK!

PS.: when i restart postfix i receiving this warning:
postmap: warning: /opt/zimbra/conf/postfix_header_checks, line 6: record is in "key: value" format; is this an alias file?

i dont know if it's the problem and how do i fix it (and do this redirect) ???

This tags and kills the spam message. The killed spam message is delivered to example@example.com and not to the user's Junk folder (D_DISCARD). Make sure you set $sa_quarantine_cutoff_level to a high value bacause else the message will not be quarantined and sent to example@example.com

THANKS A LOT maerten.
it really works here!!
I set the kill percent and the tag (at admin console) to 10 and 10, and it finally works. =D
